Description

Technical Field

[0001] The utility model relates to the technical field of composite aluminum tube processing equipment, in particular to a composite aluminum tube double-head spinning machine. Background Art

[0002] Aluminum alloy composite headers are widely used in various welded structural products due to their light weight, high strength, excellent corrosion resistance, non-magnetic properties, good formability, and excellent low-temperature performance. By using aluminum alloy instead of steel and copper for welding, the structural weight can be reduced by more than 50%. As a result, aluminum alloy composite aluminum tubes (aluminum alloy composite headers) are being used in a growing number of fields, including various heat exchangers for fuel vehicles, heat exchange components for new energy vehicle batteries, heat exchange for new energy energy storage, heat exchangers for residential and commercial air conditioners, heat exchangers for 5G base stations, heat exchangers for air-cooled islands in power plants, and heat exchangers for large-scale construction machinery.

[0003] The existing sealing process for collecting pipes is to install a plugging cap and then weld it to achieve sealing. However, the plugging cap welding method is suitable for composite aluminum collecting pipes with large diameter and appropriate wall thickness. When facing the production of small diameter and thin-walled rapid flow pipes, the production of the plugging cap is small in size, and its processing and welding process is prone to problems such as loose welding and incomplete sealing, which makes it impossible to effectively guarantee the uniformity of product quality, resulting in reduced production efficiency of the production line and a high scrap rate.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0029] The embodiment of the present application provides a double-head spinning machine for composite aluminum tubes, which solves the problem that the cap welding method in the prior art is only applicable to composite aluminum manifolds with large diameters and appropriate wall thicknesses. When facing the production of small diameter thin-walled manifolds, the welding process is prone to loose welding, incomplete sealing, etc., which makes it impossible to effectively guarantee the uniformity of product quality, resulting in a decrease in the production efficiency of the production line and a high scrap rate. The present application uses a servo drive mechanism including a feeding drive mechanism, a clamping drive mechanism and a spinning drive mechanism. After the embryo tube to be processed is clamped and fixed by a rotating fixture, three sets of servo motors and stepper motors are used to drive the spinning wheel. The two ends of the embryo tube are evenly extruded and shaped according to the set operating parameters, which simplifies the sealing production process of small diameter composite aluminum tubes and effectively improves production efficiency and sealing quality.

[0030] Please refer to the following examples for details:

[0031] Reference Figure 1 The utility model provides an embodiment of a double-head spinning machine for composite aluminum tubes, the specific structure of which includes: a work table 1, a rotating fixture 2 is detachably installed on the work table 1, and servo drive mechanisms 3 are symmetrically arranged on both sides of the rotating fixture 2. The spinning wheels 5 are driven by three groups of servo motors and stepper motors to evenly extrude and shape the two ends of the embryo tube, simplifying the sealing production process of small-diameter composite aluminum tubes. The automated processing method not only reduces the complexity of manual operation, but also reduces operating errors, effectively improves production efficiency, and ensures the uniformity of sealing quality.

[0032] Furthermore, the servo drive mechanism 3 includes a feeding drive mechanism 31, a clamping drive mechanism 32, and a spinning drive mechanism 33. The feeding drive mechanism 31 is primarily used to feed the embryo tube, the clamping drive mechanism 32 is responsible for rotating the rotary fixture 2, and the spinning drive mechanism 33 completes the spinning operation of the spinning wheel 5.

[0033] Specifically, the servo drive mechanism 3 is composed of three servo drive motors and three stepper drive motors. The drive motors drive two symmetrically arranged spinning wheels 5 through the screw slide module 4 to achieve extrusion sealing of the two ends of the small-diameter embryo tube.

[0034] Please continue reading Figure 1-Figure 3 A loading platform 6 is located behind the rotating fixture 2. A tube rack 7 is mounted on the loading platform 6, which is used to place the tubes to be processed. When the tubes need to be processed, the feeding drive mechanism 31 drives the tube rack 7 to move, and the feeding cylinder 8 cooperates to accurately feed the tubes into the rotating fixture 2 for subsequent processing.

[0035] Furthermore, the feeding drive mechanism 31 includes a first stepper motor 311, which is arranged at the front of the embryo tube rack 7. The first stepper motor 311 drives the embryo tube rack 7 to move accurately to the position directly in front of the tube clamping hole 21 of the rotating clamp 2 by driving the screw slide module 4; the feeding cylinder 8 is arranged on one side of the embryo tube rack 7, and pushes the embryo tube to be accurately fed into the tube clamping hole 21 of the rotating clamp 2.

[0036] Please continue reading Figure 1-Figure 3 The clamping drive mechanism 32 includes a first servo motor 321. The first servo motor 321 is positioned below the work surface 1 and is connected to the rotary fixture 2 through a belt drive assembly. By precisely controlling the speed and direction of the first servo motor 321, it can be ensured that the embryo tube to be processed in the rotary fixture 2 can rotate smoothly during the processing process.

[0037] Please continue reading Figure 1-Figure 3 The spinning drive mechanism 33 includes a second stepper motor 331 and a third stepper motor 332. The second stepper motor 331 and the third stepper motor 332 are symmetrically arranged on both sides of the spinning wheel 5. The second stepper motor 331 and the third stepper motor 332 jointly drive the movement of the spinning wheel 5 through the screw slide module 4 to ensure the accuracy and stability of the spinning operation.

[0038] Furthermore, a second servo motor 333 is provided on one side of the second stepper motor 331, which drives the movement of the second stepper motor 331 through the screw slide module 4; and a third servo motor 334 is also provided on one side of the third stepper motor 332, which drives the movement of the third stepper motor 332 through the screw slide module 4.

[0039] Please continue reading Figures 1-4 A method for using a spinning machine, comprising the following steps:

[0040] S1: After the device is powered on, reset the servo drive mechanism 3 to its initial position.

[0041] The second servo motor 333 and the third servo motor 334 return to the origin through the screw slide module 4, the second stepper motor 331 and the third stepper motor 332 return to the origin through the screw slide module 4, and the first stepper motor 311 returns to the origin through the screw slide module 4;

[0042] S2: After the equipment processing parameters are set, the operating table begins processing. The servo drive mechanism 3 completes the operation steps of pushing and feeding, clamping and fixing, and spinning and sealing according to the pre-set program. This continuous processing process precisely controls the execution of each link, effectively releasing the shear stress generated during processing, thereby preventing the embryo tube from being sheared during processing.

[0043] The first stepper motor 311 moves the embryo tube rack 7 to the front of the tube clamping hole 21 of the rotating fixture 2 through the screw slide module 4. The feeding cylinder 8 extends to push the embryo tube to be processed into the clamping hole of the fixture and stays there for 3 seconds. After the rotating fixture 2 clamps the embryo tube, the first stepper motor 311 drives the embryo tube rack 7 back to the origin.

[0044] After the embryo tube rack 7 returns to the origin, the second servo motor 333, the third servo motor 334, the second stepper motor 331 and the third stepper motor 332 propel the spinning wheel 5 to one side of the embryo tube at high speed through the screw slide module 4;

[0045] The first servo motor 321 drives the embryo tube to rotate at high speed through the rotating fixture 2. The second servo motor 333 and the third servo motor 334 drive the spinning wheel 5 to slowly advance through the screw slide module 4. At the same time, the second stepper motor 331 and the third stepper motor 332 drive the spinning wheel 5 to slowly retreat, so that the two ends of the embryo tube are sealed under the pressure of the spinning wheel 5.

[0046] After the second servo motor 333 and the third servo motor 334 stop, the second stepper motor 331 and the third stepper motor 332 drive the spinning wheel 5 to slowly move from both ends of the embryo tube to the middle to extrude and shape the sealing surface;

[0047] It should be explained in detail that the spindle speed of the spinning wheel 5 is 100-500 r / min, the lateral feed speed of the spinning wheel 5 is 0.1-4 mm / s, the longitudinal retreat speed of the spinning wheel 5 is 0.1-1 mm / s, the longitudinal feed speed of the spinning wheel 5 is 1 mm / s, and the clamping force of the rotary fixture 2 is 0.1-1 MPa. The specific operating parameters are shown in the following table:

[0048]

[0049] S3, after the shaping is completed, the servo drive mechanism 3 starts to move the wheel back and loosen the blanking operation. This step is to effectively reduce the indentation at both ends of the embryo tube and ensure product quality:

[0050] The second stepper motor 331 and the third stepper motor 332 drive the spinning wheel 5 to move outward at a high speed for a certain distance;

[0051] The second servo motor 333, the third servo motor 334, the second stepper motor 331 and the third stepper motor 332 sequentially drive the spinning wheel 5 back to the origin, the first servo motor 321 stops rotating, the rotating fixture 2 stops rotating and releases the processed embryo tube.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
